Dear Listserve members,
I am currently a postdoc at the Smithsonian, working on the genus Nomada
using DNA data. I am investigating two main areas: The world-wide
higher-level phylogeny of the genus and on a couple tricky species complexes
within the group.
Within the species groups, I am presently focusing on the group sometimes
known as "Gnathias"-- i.e., Nomada with bidentate mandibles (for
example, in eastern North America there are the species N. perplexa, N.
maculata, N. cuneata, N. hydrophylli, N. louisianae, N. subnigrocincta,
N. lepida, and N. ovata-- but note that I am not only interested in specimens
from eastern N. A.). I am writing ask that if you have any material
of this group collected within the past 5 to 7 years, and are willing to
allow me to sample a midleg from your specimens, would you please kindly
contact me so that we can discuss this possibility?
At the higher level, I am interested in Nomada from species-groups other
than ruficornis species-group (sensu Alexander), or anything that seems
different or particularly interesting morphologically or distributionally.
Thanks very much for any help that you can provide.
